Abstract
The well WD-lb, which was drilled in the Kakkonda field for the NEDO deep-seated geothermalresources survey project, produces fluids from a deep reservoir. The well's total flow rate of is about 10 at 3 bars wellhead pressure. Total discharge enthalpies are as high as suggesting that a two-phase feed developed in the deep reservoir. The chemical characteristics of the water of well WD-lb are similar to those of the other deep production wells in Kakkonda. The results at Kakkonda will be used to make guidelines for the development of deep-seated geothermal resources. In order to investigate the geothermal industry's technological needs for development of deep-seated geothermal resources, interviews with representatives of the industry were held.
